Photosynthesis: Overview of the light-dependent reactions
This image of the Black Sea, acquired on June 20, 2006, by the MODIS on the Aqua satellite, shows swirling blooms of phytoplankton coloring the surface waters blue and green. The large volume of freshwater flowing into the Black Sea from large European rivers, including the Danube and Dnieper Rivers, makes the sea much less salty than open oceans. The freshwater flow also delivers many nutrients, which are washed into the sea from land. These nutrients support large blooms of phytoplankton: microscopic photosynthetic organisms (algae and bacteria). The chlorophyll and other pigments the organisms use for photosynthesis change the way light reflects off the surface, and these changes are visible in satellite imagery.
What Is the Importance of Chlorophyll for Photosynthesis?
This article will examine photosynthetic efficiencies of various LEDs. Specifically, six light sources were tested for photosynthetic responses by zooxanthellae found in the stony coral (most likely of Clade C15.) The light sources include a black light (mostly UV-A produced by a fluorescent lamp), and LEDs radiating energy at peaks of 400nm (UV-A/violet), a 418nm LED (producing mostly violet with a small amount of UV-A), a blue/white LED combination peaking at white light with a peak 443nm and 457nm, a 'white' LED with a blue peak at 443nm, and red LEDs producing maximal light at 631nm and 657nm. All tests were performed when light intensity was at sub-saturating levels. Evidence suggests absorption by carotenoids is responsible for lessened photosynthetic efficiencies at 450 nm and 470 nm.
Are plants using green light for photosynthesis
These components are found within the chloroplasts of a plant cell (see diagram below).
Each type of receptor is responsible for absorbing one type of light.

Red light was second-most efficient, but the blue and UV lights were not successful; no chads floated in these environments.
Energy + 6CO2 + 6H2O ----> C6H12O6 + 6O2
Equation of Photosynthesis:
Independent Variable: time
Dependent Variable: number of leaf chads
Control: Absence of Light
Constants: concentration of baking soda in the solution, time allowed for the experiment, and the number of chads put in the solution to test.
